Additionally, each Guardian has its own Exclusive Treasure with stats tailored to its specific abilities. These are often very important to making the summoning of a Mythics Immortal form much easier.

Altar Upgrades

When you upgrade the Treasure Altar, your progress is permanent, if you switch to drawing a different Treasure later, the Altar level does not reset and stays the same.

Bonus Chance

When failing to level up a Treasure, you gain a permanent Bonus Chance (up to 10 times) increasing your overall chance for that level.
e.g. Level 10 to 11 has a 1% Base Chance. Each time you fail, you gain +0.1% chance. After 10 failed draws, you have a total of 2% chance.

Rate-Ups

When failing to draw the Exclusive Treasure, you get points for Rate-Up draws, after 10 Rate-Up points, you can do a "Rate-Up Draw" with an increased chance to obtain the Exclusive Treasure.

By default, this is 10% instead of the regular 3%. If you fail this special draw, the next Rate-Up draws will increase by 5% each time until you obtain the Exclusive Treasure.

Note: Rate-Up points and chances are shared across all Mythics and reset upon obtaining an Exclusive Treasure.
